new AP application and the old one

Somebody mentioned that my current AP is not valid any more once I apply for a new AP. Is that true?

My current AP will expire on Nov. 11. I filed a new AP application last week. Now I want to go back to China within October. So it really concens me if I can use the current AP, while the new application is still under process.
